Spaced Repetition: Beating the Forgetting Curve | AI Learning Guide

Spaced repetition is a powerful way to combat the forgetting curve. When you review material at increasing intervals, you're not just re-reading; you're actively retrieving, which strengthens the memory. For example, with vocabulary words, spacing reviews over days or weeks leads to much better retention than cramming all at once. The key is to schedule reviews just before you're about to forget, which makes the retrieval effort more effective.

What is Spaced Repetition?

Spaced repetition is a learning technique where you review material at gradually increasing intervals. This leverages the spacing effect, which shows that distributed practice leads to better long-term retention than massed practice (cramming).

Example: Learning Vocabulary

Instead of studying a list of 20 vocabulary words in one sitting, you review them on day 1, then again on day 3, day 7, and day 14. Each review strengthens the memory trace, and the increasing gaps force your brain to work harder to retrieve, which consolidates the memory.
